➀ For Vout ≥ 3.3V, Vin should be ≥ (Vout ÷ 0.85) + 0.5V.
➁ Ripple and Noise is shown at Vout=1V. See specs for details.
➂ All speciﬁcations are at nominal line voltage, Vout= 5V and full load, +25 deg.C. unless
otherwise noted. Output capacitors are 1 μF ceramic and| 10 μF electrolytic in parallel.
Input cap is 22 μF. See detailed speciﬁcations. I/O caps are necessary for our test equip-
ment and may not be needed for your application.
Vin must be 2V or higher than Vout for 3.3 to 5V outputs.

Because of the small size of these products, the product label contains a
character-reduced code to indicate the model number and manufacturing date
code. Not all items on the label are always used. Please note that the label dif-
fers from the product photograph on page 1. Here is the layout of the label:
The manufacturing date code is four characters:
date YMDX Rev. Revision level
Figure 2. Label Artwork Layout
The label contains three rows of information:
First character – Last digit of manufacturing year, example 2009
Second character – Month code (1 through 9 = Jan-Sep;
O, N, D = Oct, Nov, Dec)
Third character – Day code (1 through 9 = 1 to 9, 10 = 0 and
11 through 31 = A through Z)
Fourth character – Manufacturing information
First row – Murata Power Solutions logo
Second row – Model number product code (see table)
Third row – Manufacturing date code and revision level
